I only understood BODMAS very recently.  And that's only because I learned it from you tube videos. 🤣😂.

Ah BODMAS - or BIDMAS.

It's actually totally understandable why peopll get this incorrect - we often talk about what we are doing first and hence people re-arrange things incorrectly.

I always talk about what we are going to BRACKET or REPLACE first and get students to add brackets to what we intend to replace, keeping the order of what we write the same.

The reason is the order in which a maths statement is written creates a sentence. We talk a lot about this eg John beats Joe in a race becomes totally different if we change the order and Joe beats John in a race. 

So in 20 - 3 x 5 - the sentence is twenty take away three times five. Now you wouldn't expect someone to re-write this to be fifteen take away twenty as the sentence order is important as in any other sentence.

So I get students to look and say in BIDMAS, multiplication comes before subtraction so I'll bracket the multipliction bit.

Hence 20 - 3 x 5 becomes 20 - (3 x 5) - we then replace the bit in brackets and write it out again from left to right so 20 - 15 and so on.

The latter have doubled in 3 years. Holidays I used to be able to get for £1,500 are now £3,000. 

For giggles I just had a quick look to a 3 night stay in Centerparcs in August, as a comparison to your numbers. 3 nights in a lodge is £1000. 7 nights £2500. Of course this is just one (horrifically overpriced) option and I have no idea why people are paying so much. But yes, £1500 won't get you much at home or abroad now.

I watched an episode of Pop the Balloon recently.  It's a dating show from the US. I know, I know utter trash but I was tired and just wanted to chill out to some mindless tv.  

Talk about car crash tv, it's awful, nearly as bad as Jeremy Kyle lol.  I got sucked in and watched it just because it was so appalling. I couldn't believe just how awful it was (although at 74 nothing much surprises me these days). The contestants are for the most part pretty vile. Shallow, cruel and nasty.  None of them are really looking for love but more to be on the tv. 

Anyway one guy decided to ask the female contestants who were hoping to win a date with him a maths question which required BODMAS and which they had to do in their heads, no paper.  

 I don't know what he was trying to prove but his attitude towards the women was dreadful.  When challenged as to his motivation, his excuse was he wasn't bothered whether or not they got the answer right but whether they would attempt it.  

It was so inappropriate, most of the contestants were thrown off balance by such an off the wall question and so didnt attempt to answer, because they felt embarrassed and wrong footed, One lady gave it a shot and gave the wrong answer. His response was unbelievably patronising. 

Utter moron.....needless to say they all turned the tables on him, popped their balloons and sent him packing.  He went away with his tail between his legs, no date. Serves him right.  🤣. 

Talk about bread and circuses........

Two years ago had a one bed apartment in Portugal all inc for £1,500. Today it's £3,000. Same week too.

I am even more mathematically incompetent than I realised!!!

25 years or so ago, doing an MSc in Computing (aged 40-ish), the subject of BODMAS came up in a lecture: I felt so thick, as I hadn’t a clue what the lecturer was talking about.  Then the penny dropped… he meant “The order of precedence” …
